Question:

The following data are given for the two solid forms of HgI2 at 298 K.

, kJ mol-1 -105.4 HgI2(red) Hgl2(yellow) -102.9 1.G kJ mol-1 -101.7 (?) S, J mol-1 K-1 180 (?)

Estimate values for the two missing entries. To do this, assume that for the transition HgI2(red) → HgI2(yellow), the values of ΔrH° and ΔrS° at 25 °C have the same values that they do at the equilibrium temperature of 127 °C.
